Staff / Sr. Staff, Endpoint Client Engineer (C++)

📋 Description

• Build and harden the cross-platform C++ client runtime (macOS first).
• Architect distributed systems for speed and resilience at scale.
• Build a secure agentic harness for safe, high-performance execution.
• Own reliability, observability, security, and performance of the runtime.
• Collaborate with ML and backend teams on configuration and telemetry.

🎯 Requirements

• 10+ years in software, with 6+ yrs shipping production C++ (C++11+).
• Strong distributed systems fundamentals: routing, failover, backpressure.
• Deep experience in endpoint, client, or systems software.
• Data structures, algorithms, and performance profiling.
• Experience with agentic coding systems (Claude Code, Pi, Codex).
• BS in Computer Science or equivalent; MS preferred.

🎁 Benefits

• Own the hot path; everything the product does runs through the runtime.
• Systems problems that are actually hard; concurrency and cross-platform delivery.
• Real scale to build against; deploy and harden the runtime against production usage.
